§ 52.57 Application for renewal.

(a) Not less than 12 nor more than 36
months before the expiration of the
initial 15-year period, or any later
renewal period, any person may apply
for renewal of the certification. An
application for renewal must contain all
information necessary to bring up to
date the information and data contained
in the previous application. The
Commission will require, before renewal of certification, that
information normally contained in
certain procurement specifications and
construction and installation
specifications be completed and
available for audit if this information is
necessary for the Commission to make
its safety determination. Notice and
comment procedures must be used for a
rulemaking proceeding on the
application for renewal. The
Commission, in its discretion, may
require the use of additional procedures
in individual renewal proceedings.

(b) A design certification, either
original or renewed, for which a timely
application for renewal has been filed
remains in effect until the Commission
has determined whether to renew the
certification. If the certification is not
renewed, it continues to be valid in
certain proceedings, in accordance with
the provisions of § 52.55.

(c) The Commission shall refer a copy
of the application for renewal to the
Advisory Committee on Reactor
Safeguards (ACRS). The ACRS shall
report on those portions of the
application which concern safety and
shall apply the criteria set forth in § 52.59.
